you may as well assume the opposite

A less precise math is not always producing an inferior result.
a DX7 versus FM7 is a good example - the latter is much more precise, but sounds a bit thin and sterile (imho) in a similiar patch.
Yet it's a great device if you're exactly after a crisp and crystal clear sound.
I don't know what you used to test the compressor, but a device with a relatively narrow 'significant' frequency spectrum (like voice or guitar), can sound amazingly good due to some amount of phase shift.
The drawback is that it's not exactly predictable and relatively few tones benefit.
Since the simultaneous extinction effect (on other tones) is much easier to detect (and annoying to say at least...), the method is usually avoided.
But as another thread shows, people have even made a feature from this and supply it as a plugin - with a surface to control the 'error'
you've probably run into such a situation by pure chance.
You could repeat your test with different sources and try to detect if it's frequency depending.
Like a bass pattern that is repeatingly transposed upward.
